I read an article on the net regarding the use of 7-1/4 inch circular saw blades on a tablesaw. Besides the lower cost, the author discusses less stress on the saw’s motor, and less burning of material. He also talks about not wasting as much material due to a thinner kerf. Anyway, it seemed interesting, and I was just wondering what your thoughts were…...I would hate to try is and damage my saw in some way.

You won’t damage your saw unless it’s made for less than a 7 1/4” blade…

You will have less height to cut with, and way less on the 45 degree cuts (or any angle for that matter).

The only reason I could think why it would be that much easier on the motor is because you not taking as much of a cut /rip, or if your motor is undersized.

I have seen people do this with no problems. If you have a SawStop, you might have to check to see if there are any special considerations.

It shouldn’t hurt your saw, but you’re not likely to get results as good as those from premium 10” blades.

My cordless circular saw has a very narrow kerf and it is only a 6” blade. In theory, I could use that blade on my TS, but I wonder if the blade could stand the torque from the saw. I know I wouldn’t hurt the saw, but I might hurt the blade.

I’ve used an old 7 1/4” numerous times to cut pressure treated and nasty old plywood headed for the garbage. My Jet ProShop hasn’t shown any ill effects.
I use the circular saw blades to save the teeth on my good Woodworker II and Freud blades.

I got the idea from Matthias' website. Is this the place you’re talking about?
